Element-android: Improve fullscreen media display

[bmarty]

Especially using full immersive mode when available

• [ ] Should display image (gifs?) and video
• [ ] Seamless animation from chat to full screen (shared element transition)
• [ ] Swipe left/right to see previous/next media in timeline
• [ ] Swipe Up/Down to dismiss
• [ ] Video should have play/pause control and media progress indicator
• [ ] Option menu to share / save
• [ ] Translucent top bar with basic info (sender / date / reactions)
• [ ] Single tab to toggle topbar visibility
• [ ] Double tap image to toggle max/min zoom
• [ ] pinch to zoom in/out
• [ ] Should support not yet downloaded / downloading media
• [ ] PIP mode for video?

also it would be nice, if one would be able to swipe in the image display view to go to the next / previous image/media element (if present in the room history)

To add on the suggestion of @violoncelloCH , it would be great if swiping up or down would bring you back to the chat screen (so you don't have to press the back button). Swiping left/right could still be used to browse previous/next media

any plans to at least add image zoom? it's really annoying because you can't save an image to the internal memory nor zoom, which makes sending big images/screenshots completly useless

@Destroyer Did you happen to try it in unencrypted rooms? Because pinch to zoom should normally work (see #75). I've opened #1123 for e2ee rooms, because there it doesn't work for me.

[Destroyer]

I haven't because I use riotx e2e DMs 99% of the time, but you're competly right, it works for me in non-e2e rooms.

"Video should have play/pause control and media progress indicator", would be quite useful. There is no way to move back in the video.

Can we also add #1540 here?
